Eye Tracking Based Selection of a User Interface (UI) Element Based on Targeting Criteria

2. The method of claim 1, wherein determining that the first targeting criterion is satisfied includes determining that a first gaze position is directed to within the first selection region for at least a threshold amount of time, and wherein determining that the second targeting criterion is satisfied includes determining that a second gaze position is directed to within the second selection region for at least the threshold amount of time.

4. The method of claim 1, wherein selecting the first UI element is further based on determining, based on the eye tracking data, that a gaze movement from the first selection region to the second selection region satisfies a scanning criterion.

5. The method of claim 4, wherein the first UI element is further associated with a scanning region positioned within the first UI element, wherein the scanning region connects the first selection region with the second selection region, and wherein determining that the scanning criterion is satisfied includes determining that the gaze movement is within the scanning region.

6. The method of claim 5, wherein determining that the scanning criterion is satisfied includes determining that the gaze movement does not move outside of the scanning region.

7. The method of claim 1, further comprising, in response to determining that the first targeting criterion is satisfied, increasing a size of the second selection region.

8. The method of claim 1, wherein the second targeting criterion is de-activated before determining that the first targeting criterion is satisfied, the method further comprising, in response to determining that the first targeting criterion is satisfied, activating the second targeting criterion.

10. The method of claim 9, wherein the third selection region partially overlaps with the first selection region in a first overlapping region, and wherein reducing the size of the third selection region reduces a size of the first overlapping region.

12. The method of claim 9, further comprising, in response to determining that the first targeting criterion is satisfied, prioritizing the first selection region over the third selection region.

15. The method of claim 1, wherein the first selection region is associated with a first dimensional characteristic, and wherein the first dimensional characteristic is based on a depth between the first UI element and an electronic device.

16. The method of claim 1, wherein determining that the first targeting criterion is satisfied is based on a gaze cone and a depth between the first UI element and an electronic device.

18. The method of claim 17, wherein the gaze cone is positioned such that the gaze vector runs through the center of the gaze cone.

19. The method of claim 16, wherein the gaze cone radially increases as the depth increases.
